Playlist Configuration and Preview

ABSTRACT

In some implementations, a user can play a music track from a dynamically generated playlist. The user can provide input indicating that the user likes or dislikes the music track and the playlist can be adjusted based on the user input. In some implementations, information can be presented to the user so that the user can preview changes to the playlist before the changes are made to the playlist. In some implementations, a user can adjust playlist criteria (configuration) by adjusting specific music characteristics. In some implementations, a user can adjust playlist criteria by manipulating a list of representative music tracks. In some implementations, a user can compare the user&#39;s playlist to playlists of other users.

TECHNICAL FIELD

The disclosure generally relates to media playback and playlist configuration.

BACKGROUND

Nearly everyone has access to digital media these days. People own digital audio devices that store digital music libraries containing thousands of music tracks. Users often listen to music streamed over the internet. Often these devices and technologies allow users to automatically generate playlists or radio stations based on a representative music track, artist, genre or other user-specified criteria. As music tracks are played from the playlist or radio station, user feedback can be received for a music track. The user can indicate whether the user likes or dislikes a music track and the user's likes or dislikes can cause an adjustment in the playlist or radio station criteria that effect which music tracks are played in the future.

SUMMARY

In some implementations, a user can play a music track from a dynamically generated playlist. The user can provide input indicating that the user likes or dislikes the music track and the playlist can be adjusted based on the user input. In some implementations, information can be presented to the user so that the user can preview changes to the playlist before the changes are made to the playlist. In some implementations, a user can adjust playlist criteria (configuration) by adjusting specific music characteristics. In some implementations, a user can adjust playlist criteria by manipulating a list of representative music tracks. In some implementations, a user can compare the user's playlist to playlists of other users.

Particular implementations provide at least the following advantages: A user can easily preview changes to a playlist and avoid changes that can negatively effect the playlist. The user is given greater control over playlist criteria and the music tracks associated with the playlist.

Details of one or more implementations are set forth in the accompanying drawings and the description below. Other features, aspects, and potential advantages will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION Dynamic Playlists

FIG. 1 illustrates a system 100 for generating dynamic playlists. In some implementations, a user can play media associated with a playlist on a playback device 102. For example, playback device 102 can be a laptop computer, desktop computer, handheld music player, a smartphone, a tablet computer or any other device that can be configured to play back music media.

In some implementations, the playlist can be generated locally on playback device 102. For example, the playlist can be generated by music engine 104 based on media library 106 (e.g., digital music library) that is stored on or accessible to playback device 102. For example, music engine 104 can be a media application on playback device 102 that manages and plays music associated with playlists. Media library 106 can include a collection of music tracks that can be associated with a playlist and played on playback device 102.

In some implementations, the playlist can be generated at music service 108. For example, the music service 108 can be an Internet-based service and music tracks can be selected for the playlist by music engine 110 and can be streamed from music service 108 over network 114 to playback device 102. The music tracks for the playlist can be identified by music engine 110 by matching the playlist criteria to characteristics of music tracks stored in a music database 112 or music library 106. In some implementations, music database 112 can store music characteristics associated with music tracks. In some implementations, music database 112 can store playlist configuration for multiple users. For example, music database 112 can store playlist criteria for multiple playlists associated with multiple users.

In some implementations, a playlist (or radio station) can be a dynamically and/or automatically generated sequence of music tracks. The music tracks can be selected for the playlist based on user-specified criteria. In some implementations, a user can select a music track and the music track can serve as a basis for creation of the playlist. For example, the music track can have a certain set of characteristics (e.g., fast tempo, country genre, string instruments, melodic lyrics, etc.) and the characteristics of the selected music track can be the criteria by which future music tracks are selected for the playlist. The playlist can be dynamically generated. For example, the playlist does not have to be a discrete set of music tracks. Music tracks can be added and removed from the playlist in real-time based on the playlist criteria. For example, as a current music tracks is being played, the next music track (or the next five music tracks, next ten music tracks) can be selected and added to the playlist queue and automatically played when the current music track ends.

Receiving User Feedback

FIG. 2 illustrates an example graphical interface 200 for playing media from a playlist. For example, graphical interface 200 can correspond to an interface of playback device 102. In some implementations, graphical interface 200 can present graphical element 202 for initiating playback of a music track from a playlist. For example, graphical element 202 can be a play button which when selected causes a music track from the playlist to be played by a playback device.

In some implementations, graphical interface can display an image 204 corresponding to the currently playing music track. For example, image 204 can be artwork corresponding to an album associated with the currently playing track. In some implementations, graphical interface 200 can include progress bar 206 and indicator 208. For example, progress bar 206 can represent how long a music track is and indicator 208 can indicate a position in the music track that corresponds to the portion of the music track that is currently being played.

In some implementations, graphical interface 200 can include graphical element 210 for skipping to the next music track in the playlist. For example, if a user wants to play the next music track in the playlist before the currently playing music track is completed, the user can select graphical element 210 to cause the next music track to be played. In some implementations, graphical interface 200 can include graphical element 212. For example, graphical element 212 can be selected to cause a playlist configuration interface to be displayed, as described further below with reference to FIG. 6.

In some implementations, graphical interface 200 can include music track list 214. For example, music track list 214 can be a list of the next five music tracks that will be played in the playlist. As each music track in music track list 214 is played, a newly selected music track can be added to the playlist. Music track list 214 can include icons for each music track in the music track list. For example, the icons can be images of album artwork associated with each music track.

In some implementations, a user can manipulate the music tracks in music track list 214. For example, the user can select a music track (e.g., icon) in music track list 214 and delete the music track from music track list 214. The user can perform a drag and drop operation on a music track in music track list 212 to rearrange the order of the upcoming music tracks in music track list 214. For example, if a user sees a music track in music track list 214 that the user really likes, the user can drag the music track to the front (e.g., left end) of music track list 214 to cause the music track to be played sooner than the other music tracks in music track list 214.

In some implementations, graphical interface 200 can include graphical elements 216 and 218 for allowing a user to provide feedback regarding the user's impression or opinion of the currently playing music track. For example, a user can select graphical element 216 to indicate that the user likes the currently playing music track. The user can select graphical element 218 to indicate that the user dislikes the currently playing music track. Selection of graphical element 216 or 218 can indicate whether the user believes the currently playing track is suitable for the playlist.

In some implementations, when a user selects graphical element 216 (e.g., like button) or graphical element 218 (e.g., dislike button) the user's selection can effect which music tracks are selected for the playlist. For example, if a user indicates that the user dislikes a music track (e.g., the user selects graphical element 218), the criteria by which music tracks are selected for the playlist will be adjusted so that music tracks having similar characteristics to the disliked music track will be less likely to be selected for playback in the future. If the user indicates that the user likes a music track (e.g., the user selects graphical element 216), the criteria by which music tracks are selected for the playlist will be adjusted so that music tracks having similar characteristics to the liked music track will be more likely to be selected for playback in the future.

In some implementations, manipulation of music track list 214 can effect which music tracks are selected for the playlist. For example, when a music track is deleted from music track list 214, the deletion can have the same effect when the user selects graphical element 218. The characteristics of the deleted music track will be considered when selecting future music tracks, for example. Music tracks having characteristics similar to the deleted music track will be less likely to be played in the future.

Confirming Changes to Playlist Criteria

FIG. 3 illustrates an example graphical interface 300 for confirming changes to a playlist. For example, graphical interface 300 can be displayed in response to the user selecting graphical element 216 or graphical element 218. Graphical interface 300 can be displayed in response to the user deleting a music track from music track list 214, for example. In some implementations, graphical interface 300 can include information area 302. For example, information area 302 can display information describing what effect the user's selection of graphical element 216 (e.g., like) or graphical element 216 (e.g., dislike) will have on the selection of future music tracks for the playlist. Information area can describe the characteristics of the liked or disliked music track and indicate that music tracks having similar characteristics are more likely or less likely to be played in the future.

In some implementations, graphical interface 300 can also include graphical element 304 for indicating a reason why the user likes or dislikes the music track. For example, graphical element 304 can be a pull-down menu including a list 306 of reasons why a user would like or dislike a music track. The user can select one of the reasons from list 306 to indicate the reason why the user likes or dislikes a music track. In some implementations, the user's reason for liking or disliking a music track can be uploaded to music service 108 and can be used to modify the classification or characteristics of the music track stored in music database 112. For example, if the user selects “wrong genre” as a reason why the user dislikes a music track, the music track can be flagged at music service 108 so that the characteristics associated with the music track (e.g., the assigned genre) can be reevaluated and adjusted in music database 112.

In some implementations, graphical interface 300 can include graphical element 308 for canceling a user's like or dislike input for a music track. For example, when a user selects graphical element 308 the user's selection of graphical element 216 or graphical 218 will be disregarded and no adjustment to the playlist will be made. In some implementations, graphical interface 300 can include graphical element 310 for removing only the current music track from the playlist. For example, when a user selects graphical element 310, the user's input (e.g., like or dislike input) will only effect how frequently the current music track is played and the playlist criteria will not be adjusted. In some implementations, graphical interface 300 can include graphical element 312 for accepting the user's like or dislike input. For example, when a user selects graphical element 312, the changes to the playlist described in information area 302 and any other playlist input or configuration change will be applied to the playlist. In some implementations, selection of graphical element 308, 310 or 312 causes graphical interface 300 to close and graphical interface 200 to be displayed.

In some implementations, graphical interface 300 can include graphical element 314 for presenting a preview of changes to the playlist. For example, when a user selects graphical element 314 an interface can be displayed that presents a detailed preview of adjustments that will be made to the playlist if the user's like or dislike input is applied to the playlist, as described in detail with reference to FIG. 5 below. In some implementations, graphical interface 300 can include graphical element 316 for editing the characteristics of a music track.

Adjusting Track Characteristics

FIG. 4 illustrates an example graphical interface 400 for editing the characteristics of a music track. For example, graphical interface 400 can be displayed in response to a selection of graphical element 316 of FIG. 3. In some implementations, graphical interface 400 can include graphical elements 402-414 for presenting, editing and/or adjusting the characteristics of a music track. For example, a music track can be associated with characteristics describing the music track. Music service 110 (e.g., people working for the music service, music critics) can assign characteristics to a music track that are descriptive of the content of the music track which allow for classification and comparison of music tracks. When graphical interface 400 is invoked or initially displayed, graphical elements 402-414 can be configured to present the assigned characteristics.

In some implementations, a user can change characteristics associated with a music track by manipulating graphical elements 402-414. For example, graphical elements 402-414 can be manipulated by a user to adjust the characteristics of the music track that a user liked or disliked by selecting graphical element 216 or 218. For example, if the user believes that the music track does not belong in the user's playlist or that the characteristic values assigned to the music track are wrong, the user may wish to indicate different characteristic settings that better represent the music track.

In some implementations, a user can change the genre associated with a music track by selecting graphical element 402. For example, graphical element 402 can be a pull-down menu that lists music genres and a user can change the genre associated with the music track by selecting a new genre from the pull-down menu's list. In some implementations, the genre currently associated with the music track can be displayed at the top of the pull-down menu's list. The genre currently associated with the music track can be displayed when the pull-down list is not displayed.

In some implementations, a user can change characteristics of a music track by adjusting graphical elements 404-414. For example, graphical elements 404-414 can correspond to music characteristics such as pitch, rhythm, dynamics, timbre and texture. Graphical element 404 can correspond to tempo (e.g., speed or pace of the track), for example. If the user believes that the tempo value currently assigned to the music track is not accurate, the user can adjust graphical element 404 to represent the user's opinion of the track's tempo. For example, graphical element 404 can be a slider element where the left end of the slider corresponds to a slow tempo and the right end of the slider corresponds to a fast tempo. The user can slide position indicator 416 left or right along the slider to adjust the tempo assigned to the music track. The adjustment of graphical element 404 does not change the content of the music track, the adjustment merely changes the descriptive characteristics assigned to the music track. Other music characteristics can be adjusted by manipulating graphical elements 404-414. For example, characteristics associated with the feelings invoked in the user by a music track can be represented and adjusted by graphical elements 404-424. These characteristics can correspond to a mood invoked in the listener (dark, light, joy, sadness, etc.), for example.

In some implementations, graphical interface 400 can include a graphical element 420 for submitting the characteristics edits to music service 108. For example, once the user has made the adjustments to the assigned characteristics of the music track, the user can submit the adjustments to the music service for consideration. For example, the music service can manage metadata (including music track characteristics) associated with music tracks in music database 112 and update playback device 102 with the music track metadata when the music track metadata changes. Music service 108 can adjust the characteristics of the music track based on the user's input to graphical interface 400, for example. Music service 108 can transmit the adjusted characteristics to the user's playback device to update music library 106 so that music engine 104 an identify music tracks for playlists based on the updated metadata, for example. If music service 108 is configured to stream playlist music tracks to playback device 102, music service 108 can use the adjusted music track characteristics in music database 112 to determine which playlists should include the music track. For example, music engine 104 and/or music engine 110 can match playlist criteria to music track characteristics to determine a match between music tracks and playlists.

In some implementations, graphical interface 400 can include graphical element 418 for resetting the characteristics of a music track. For example, if the user has made adjustments to the track's characteristics on graphical interface 400, the user can reset the music track's characteristics back to their previous values (e.g., reset to the characteristics defined by music service 108) by selecting graphical element 418. In some implementations, the user can select graphical element 422 to return to graphical interface 300.

Playlist Adjustment Preview

FIG. 5 illustrates an example graphical interface 500 for presenting a preview of changes to a playlist. For example, graphical interface 500 can be presented in response to a user selecting graphical element 314 of FIG. 3. Graphical interface 500 can present a preview of changes to a playlist that will result from a user expressing or indicating a liking (e.g., selecting graphical element 216) or disliking (e.g., selecting graphical element 218) for a music track, for example.

In some implementations, graphical interface 500 can present a preview of changes to playlist criteria. For example, playlist criteria can include music characteristics such as the characteristics associated with music tracks described above. The playlist criteria (characteristics) can be presented as a value within a range of values and represented by graphical elements 502-510, for example. Graphical element 510 can represent a range in tempo, for example. In some implementations, graphical elements 502-510 can indicate current values and provide a preview of future values for the playlist criteria. For example, current position indicator 512 can indicate the current value for the tempo characteristic of the playlist criteria. Preview indicator 514 can indicate the future value for the tempo characteristic of the playlist criteria. For example, preview indicator 514 can indicate what the value of the tempo characteristic will be if the user's like or dislike indication is applied to the playlist. Thus, the user can quickly identify how the user's feedback will effect the playlist criteria.

In some implementations, graphical interface 500 can present a preview of changes to music track selection resulting from a user indicating a like or dislike of a music track. For example, graphical interface 500 can display a list 516 of music tracks representing the current playlist criteria. In some implementations, list 516 can include icons or images associated with each music track. For example, the icons or images can correspond to album artwork associated with each music track. The music tracks in list 516 can be the five music tracks that best represent the current playlist criteria, for example. In some implementations, list 516 can present a list of the next songs to be played in the playlist. For example, list 516 can present the next five songs that will be played. In this implementation, list 516 can correspond to music track list 214.

In some implementations, graphical interface 500 can display a list 518 of music tracks representing future playlist criteria. For example, list 518 can present a list of music tracks representing changes in the playlist criteria that will result from the user liking or disliking a music track. In some implementations, list 518 can include icons or images associated with each future music track. For example, the icons or images can correspond to album artwork associated with each future music track. The music tracks in list 518 can be the five music tracks that best represent the future playlist criteria, for example. In some implementations, list 518 can present a list of the next songs that will be played if the playlist criteria are changed. For example, list 518 can present the next five songs that will be played based on the changed criteria.

In some implementations, a user can change between listing representative music tracks and listing upcoming music tracks in lists 516 and 518. For example, graphical element 520 can be selectable to toggle between representative music track lists and upcoming music track lists. In some implementations, the underlined text of graphical element 520 can be selected to switch to the upcoming music track lists, for example. When the upcoming music tracks lists are displayed in lists 516 and 518, the text of graphical element 520 corresponding to the representative lists can be underlined and the user can select the underlined text to display the representative music tracks lists.

In some implementations, a user can visually compare list 516 and list 518 to determine how changes to the playlist criteria will change which songs will be selected for the playlist. For example, by examining and comparing list 516 and list 518 the user can quickly identify that song 3 and song 5 in the preview list are different than song 3 and song 5 in the current list of tracks. This visual comparison can give the user a better idea of how music track selection will change in response to the change in playlist criteria. The user can select graphical element 422 to return to graphical interface 300 of FIG. 3.

Playlist Configuration

FIG. 6 illustrates an example graphical interface 600 for viewing and manipulating playlist criteria. For example, graphical interface 600 can be displayed in response to a user selecting graphical element 212 of FIG. 2. In some implementations, graphical interface 600 can include graphical elements 602-610 for displaying and manipulating playlist criteria. For example, graphical elements 602-610 can correspond to characteristics of music that define the playlist and can include the music track characteristics described above. In some implementations, graphical elements 602-610 can be slider bars that can be manipulated by a user to adjust the value of playlist criteria or characteristics. For example, if graphical element 610 corresponds to a range of tempo values, the user can select and drag position indicator 612 to different positions along the slider bar of graphical element 610 to set a new tempo value for the playlist. This change in tempo value can result in selecting music tracks for the playlist in the future that have faster or slower tempos, for example.

In some implementations, graphical interface 600 can include a representative music track list 614. For example, list 614 can correspond to list 516 of FIG. 5. Representative music track list can display images or icons associated with the tracks in the list. In some implementations, list 614 can present a list of music tracks that best represent the playlist criteria. In some implementations, list 614 can be updated in real-time as changes are made to the playlist criteria. For example, as adjustments are made to graphical elements 602-610, list 614 can be updated to represent the music tracks that best represent the adjusted criteria.

In some implementations, representative music track list 614 is adjustable to change playlist criteria. For example, a user can rearrange the music tracks in list 614 to emphasize features of certain music tracks. For example, if a user moves a music track from position five to position one in list 614, the playlist criteria can be adjusted to give more weight to the characteristics of the moved music track. In some implementations, a user can replace a music track in list 614 to cause a corresponding adjustment in the playlist criteria. For example, a user can select an image list 614 to invoke an interface (not shown) for selecting a different music track. Once a different music track is selected, the music track can replace the music track that was selected for replacement. In some implementations, the characteristics of the replacement music track can be incorporated into the playlist criteria. In some implementations, as music tracks in list 614 are manipulated, moved or replaced, graphical elements 602-610 can be adjusted to reflect the changes in the playlist criteria that resulted from the manipulation of list 614.

In some implementations, the characteristics of representative music tracks can be averaged to determine the playlist criteria values. For example, as a user replaces music tracks in representative music tracks list 614, the values of characteristics associated with the added music track can be averaged with the existing music tracks in list 614 to determine the values of corresponding playlist criteria. For example, if representative list 614 includes music tracks with tempo values 5, 8, 6, 9 and 7 on a scale of one to ten (1-10 scale), then the value of the playlist criteria corresponding to tempo can be set to seven. In some implementations, the most frequent value will be used to determine a value for playlist criteria. For example, the music tracks in representative list can be associated with different genres. Genres values cannot be averaged, thus the genre that appears most frequently in the representative list can be used as the genre in the playlist criteria.

In some implementations, a user can select graphical element 616 to reset the playlist criteria to their former values. For example, if a user has adjusted the playlist criteria values by manipulating graphical elements 602-610 or by manipulating representative music track list 614, then the playlist criteria can be reset to their previous values (e.g., the values to which they were set when graphical interface 600 was invoked) by selecting graphical element 616. In some implementations, changes to the playlist criteria can be saved when the user selects graphical element 422. For example, the changes to the playlist criteria can be saved to playback device 102 and/or uploaded to music service 108. In some implementations, graphical interface 600 can be closed and graphical interface 200 can be displayed in response to a user selecting graphical element 422. In some implementations, a user can compare the user's playlist to the playlists of other users by selecting graphical element 618.

Comparing Users' Playlists

FIG. 7 illustrates an example graphical interface 700 for comparing users' playlists. For example, graphical interface 700 can allow a user to compare the user's playlist criteria to the playlist criteria of other users. For example, music service 108 can manage users' playlists. As a user updates or modifies playlist criteria, the playlist criteria can be uploaded to music service 108. Thus, the media service can manage playlist criteria for many users.

In some implementations, when graphical interface 700 is invoked on playback device 102, a request for other users' playlists can be transmitted to music service 108. For example, the request can include playlist criteria and/or representative music tracks of the user's playlist. The request can include the song, artist, genre or other criteria upon which the playlist is based. The music service can determine similar playlists from among the playlists associated with other users. For example, the playlist criteria and/or representative songs can be compared to the playlist criteria and/or representative songs of other users' playlists to determine similarities between the playlists.

In some implementations, only the playlists that have different playlist criteria or representative music tracks will be displayed in graphical interface 700. For example, graphical interface 700 can present music tracks that are representative of different playlists so that a user can compare the representative tracks of the user's playlist to the representative tracks of other users' playlists. By comparing the representative tracks of other playlists, the user can identify ways to adjust the user's playlist criteria to produce a better playlist. For example, the user can incorporate representative songs from other users' playlists into the user's playlist to make a better playlist.

In some implementations, graphical interface 700 can include representative track list 702. Track list 702 can include music tracks that represent the playlist criteria of the user, for example. Graphical interface 700 can include representative track list 704. For example, track list 704 can include music tracks that represent the playlist criteria of another user (e.g., user 1). Graphical interface 700 can include graphical element 706 to display more playlist information for other users. For example, if graphical interface 700 displays playlist information for other users 1-3, then selection of graphical element 706 will result in playlist information for other users 4-6 to be displayed.

In some implementations, a user can select graphical element 708 to view detailed playlist comparison information. For example, a user can select the text of graphical element 708 (e.g., corresponding to user 3) to display an interface for comparing the details of user three's playlist and the details of the user's playlist. In some implementations, a user can select graphical element 422 to cause graphical interface 600 to be displayed.

Detailed Playlist Comparison

FIG. 8 illustrates an example graphical interface 800 for presenting detailed playlist comparison information. In some implementations, graphical interface 800 can display a list 802 of music tracks representative of the user's playlist and a list 804 representative of another user's playlist. Displaying list 802 and list 804 can allow a user to easily make a visual comparison of playlist criteria. In some implementations, a user can adjust the playlist criteria for the user's playlist by manipulating list 802 and 804. For example, if the user sees a music track in list 804 that the user likes, the user can select and drag the music track from list 804 into list 802. The user can select and drag the track into a position in list 802 and the list can automatically adjust to make room for the selected track. For example, the last music track in list 802 can be removed to make room for the selected music track from list 804. In some implementations, the characteristics of the added music track can be incorporated into the playlist criteria. For example, the playlist criteria can be adjusted to account for the added music track and account for the removed music track.

In some implementations, graphical elements 806-814 can display playlist criteria values associated with the playlists displayed on graphical interface 800. For example, graphical elements 806-814 can correspond to playlist criteria (e.g., music characteristics), as described above. For example, graphical element 814 can correspond to a range of tempo values. Position indicator 816 can correspond to the tempo value for the user's playlist (e.g., a tempo value of three). Position indicator 818 can correspond to the tempo value for the other user's playlist (e.g., a tempo value of six). Thus, a user can quickly compare the user's playlist criteria to the playlist criteria of other user's.

In some implementations, a user can adjust graphical elements 806-814 to cause a corresponding adjustment in playlist criteria. For example, a user can move position indicator 816 along the slider bar of graphical element 814 to adjust the playlist criteria value for tempo. The user can make the tempo adjustment to change to tempo value of the user's playlist to be closer to the tempo value of the comparison playlist (e.g., the other user's playlist). In some implementations, the user can select graphical element 422 to exit graphical interface 800 and cause graphical interface 600 to be displayed.

Additional Representations of Music Characteristics

In some implementations, the music characteristics and/or playlist criteria can be represented and adjusted using a variety of graphical interface elements. For example, the music characteristics and playlist criteria values represented by graphical elements 304-314, 402-410, 602-610 and/or 806-814 can be presented using color, shapes, sizes, volumes and/or other graphical elements.

In some implementations, a graphical interface can be displayed where each music characteristic or playlist criteria is represented by a different color. For example, tempo can be represented by the color red. In some implementations, the value for the music characteristic or playlist criteria can be represented by the volume, area, amount or intensity of the color displayed. For example, a large area of red color displayed on the graphical interface can represent a fast tempo. A small area of red color can represent a slow tempo. In some implementations, the user can draw areas of color to change music characteristics associated with a track or playlist criteria. Thus, a graphical interface having color representations of music characteristics or playlist criteria can present many different colors representing the various music characteristics and/or playlist criteria.

In some implementations, the colors can be colors that fill geometric shapes on the graphical interface and the sizes of the geometric shapes can represent a value of the corresponding music characteristic and/or playlist criteria. For example, the user can change the sizes and dimensions of the geometric shapes to cause a corresponding change in the music characteristic or playlist criteria.

In some implementations, music characteristics and playlist criteria values can be represented on a two dimensional grid. For example, a two dimensional grid can be displayed where one dimension represents tempo and the other dimension represents timbre. The two dimensional grid can include a position indicator that can be moved by the user within the two dimensional grid to specify the values for tempo and timbre.
